Analysis of the concept of Java technology stack and its practical application

To understand the concept of Java technology stack and its practical application, specific code examples are required

Title: In-depth understanding of Java technology stack and its practical application

Introduction:
As a technical architecture widely used in the field of software development, the Java technology stack has become the first choice for many developers. It consists of a series of technologies that work together, covering all aspects of development from front-end to back-end. This article will delve into the concept of the Java technology stack, introduce its common technology components, and provide some practical code examples to help readers better understand and apply the Java technology stack.

1. Overview of Java Technology Stack
Java technology stack refers to a series of technical components used to develop various applications. It covers front-end development, back-end development, database management, server deployment and testing. Common Java technology stack components include HTML, CSS, JavaScript, Java Servlet, JavaServer Pages (JSP), Spring framework, Hibernate framework, MySQL database, etc. These components are introduced separately below.

2. Introduction to technology stack components

  1. Front-end development
    Front-end development refers to the work responsible for building the user interface. In the Java technology stack, HTML, CSS and JavaScript are the basis of front-end development. Here is a simple HTML example:
<!DOCTYPE html>
<html>
<head>
<title>示例页面</title>
</head>
<body>
<h1 id="Hello-World">Hello, World!</h1>
</body>
</html>

  1. Backend Development
    Backend development refers to the work of handling server-side logic. Commonly used back-end development components in the Java technology stack include Java Servlets and JavaServer Pages (JSP). The following is a simple Java Servlet example:
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class HelloServlet extends HttpServlet {
  public void doGet(HttpServletRequest request,
    HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head><title>Hello, World!</title></head>");
    out.println("<body>");
    out.println("<h1 id="Hello-World">Hello, World!</h1>");
    out.println("</body></html>");
  }
}

  1. Database Management
    Database management refers to the work of using a database to store and manage data. In the Java technology stack, the commonly used database component is MySQL. The following is a simple Java code example that demonstrates how to connect to a MySQL database and perform query operations:
import java.sql.*;
public class MySQLConnect {
  public static void main(String[] args) {
    String url = "jdbc:mysql://localhost:3306/mydatabase";
    String username = "root";
    String password = "password";
    try {
      Connection connection = DriverManager.getConnection(url, username, password);
      Statement statement = connection.createStatement();
      ResultSet resultSet = statement.executeQuery("SELECT * FROM users");
      while (resultSet.next()) {
        System.out.println(resultSet.getString("username"));
      }
      connection.close();
    } catch (SQLException e) {
      e.printStackTrace();
    }
  }
}

  1. Server deployment
    Server deployment refers to deploying the application to the server and making it The process of making it accessible on the Internet. Commonly used server components include Apache Tomcat, JBoss, etc. The following is a simple Tomcat server configuration file example:
<Server port="8005" shutdown="SHUTDOWN">
  <Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <Engine name="Catalina" defaultHost="localhost">
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Context path="" docBase="myapp" debug="0" reloadable="true" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t "%r" %s %b" />
      </Host>
    </Engine>
  </Service>
</Server>

  1. Testing
    Testing is an important part of ensuring that the application is running properly. In the Java technology stack, commonly used testing frameworks include JUnit and Mockito. The following is a simple JUnit test example:
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class CalculatorTest {
  @Test
  public void testAddition() {
    Calculator calculator = new Calculator();
    int result = calculator.add(2, 3);
    assertEquals(5, result);
  }
}

Conclusion:
This article introduces the concept of Java technology stack and its common components, and provides corresponding code examples. It is hoped that through these practical examples, readers will have a deeper understanding of the principles and applications of the Java technology stack. In the actual development process, the corresponding technical components can be selected as needed, and modified and adjusted according to the sample code to meet specific business needs. Only by continuous learning and practice can we continue to make progress in the field of Java technology stack.

Write a Java program to calculate the area and perimeter of a rectangle using the concept of classes Write a Java program to calculate the area and perimeter of a rectangle using the concept of classes Sep 03, 2023 am 11:37 AM

The Java language is one of the most commonly used object-oriented programming languages ​​in the world today. The concept of classes is one of the most important features of object-oriented languages. A class is like a blueprint for an object. For example, when we want to build a house, we first create a blueprint of the house, in other words, we create a plan that shows how we are going to build the house. According to this plan we can build many houses. Likewise, using classes, we can create many objects. Classes are blueprints for creating many objects, where objects are real-world entities like cars, bikes, pens, etc. A class has the characteristics of all objects, and the objects have the values ​​of these characteristics. In this article, we will write a Java program to find the perimeter and faces of a rectangle using the concept of classes
